Adult Hypophosphatemic Osteomalacia.

A 32-year-old lady of Asian descent presented with pain and severe stiffness of the back and hips progressively worsening over several years. She was diabetic but had no past medical history of rickets or renal disease. On examination she was of short stature with marked thoracic kyphosis and flattening of the lumbar spine.

Development of a screening assay for surrogate markers of CHK1 inhibitor-induced cell cycle release.

Chk1 is a key regulator of the S and G2/M checkpoints and is activated following DNA damage by agents such as the topoisomerase I inhibitor camptothecin (CPT). It has been proposed that Chk1 inhibitors used in combination with such a DNA damaging agent to treat tumors would potentiate cytotoxicity and increase the therapeutic index, particularly in tumors lacking functional p53. The aim of this study was to determine whether gene expression analysis could be used to inform lead optimization of a novel series of Chk1 inhibitors.

Inhibitors of Helicobacter pylori ATPase Cagalpha block CagA transport and cag virulence.

With the steadily increasing occurrence of antibiotic resistance in bacteria, there is a great need for new antibacterial compounds. The approach described here involves targeting virulence-related bacterial type IV secretion systems (TFSSs) with small-molecule inhibitors. The cag TFSS of Helicobacter pylori was chosen as a model, and novel inhibitors directed against the cag VirB11-type ATPase Cagalpha were identified.

Recent developments in adjuvants for vaccines against infectious diseases.

New generation vaccines, particularly those based on recombinant proteins and DNA, are likely to be less reactogenic than traditional vaccines, but are also less immunogenic. Therefore, there is an urgent need for the development of new and improved vaccine adjuvants. Adjuvants can be broadly separated into two classes, based on their principal mechanisms of action; vaccine delivery systems and 'immunostimulatory adjuvants'.
